JOSIAH J. PHILBRICK, OF MOBILE, ALA., ASSIGNCR, BY MESN E ASSIGNMENTS,TO THE BLOUN'I STAVE MACHINE COMPANY, OF CHICAGO, ILTJ- STAVE-JOINTINGMACHINE.

SPECIPICATION forming part of Letters Patent No, 360,617, dated April 5,1887.

Application filed October 20, 1884. Serial No. 146,135. (No model.)

To all whom it may concern:

Be it known that I, JOSIAH J. PHILBRICK, a citizen of the United States,residing at Mo bile city, in the county of Mobile and State of Alabama,have invented a certain new and useful Improvement in Stave- J ointingMachines, which is fully set forth in the following specification,reference being bad to the accompanying drawings, in which- Figure 1 isa side elevation of a machine embodying my invention; Fig. 2, asectional view of the same on the line at as of Fig. 1; Fig. 3, a planview; Fig. 4, a sectional view on the line y y of Fig. 3, and Fig. 5 adetail View.

Like letters refer to like parts in all the figures.

My invention relates to machines for jointing barrel-staves; and itconsists in certain novel features which I will now proceed to describe,and then specifically point out in the claims.

My machine is intended for use in connection with a stave-planingmachine and a crozing and ehamfering machine, for which I have madeapplication for Letters Patent-for the former by anapplication of evendate here with, and for the latter by application No. 13-l,869, filedJune 14, 1884.

In the drawings, A represents the frame of the machine provided with alongitudinal bed or way, 13, to support the stave. In suitable journalsin the frame are mounted the pairs of feed-rollers C C C C", driven byany suitable means. In the present instance the upper and lower rollsare connected at one side by pinions C, attached to their shafts, and atthe other end the lower feed-roller shafts have pinions 0", meshing witha gear, D, mounted on the shaft d of a sprocket-wheel, D, driven by asuitable belt or chain. The upper feedrolls are preferably and are shownas mounted. in sliding boxes E, held down by springs E, the tension ofwhich may be regulated by screws 6, so as to give a yielding pressure.At the forward end of the bed B are located the guide-plates B, mountedon screw-rods B", having their ends threaded in opposite directions, sothat by turning the said screw-rods the guide-plates may besimultaneously adjusted toward or from each other.

The central portion of the bed B is provided with knife-edged guides b,against which the stave is held by means of a pressure-roller, F,loosely mounted on a shaft, F, resting 1n notched brackets F and helddown in place by springs f, attached to the frame and to the ends of theshaft, whereby a yielding pressure is obtained. The tension of thesesprings may be regulated by nuts f on the upper end of the bolts f whichconnect the springs to the shaft F.

Above the bed B, and between the front and rear sets of feed-rollers, isarranged a tractionwheel, G, secured to a shaft, G, preferably mountedin the same manner as the upper feed-rollers, as shown. The distancebetween the bed and the traction-wheel is such that when a stave is fedbetween them the serrated or toothed periphery of the wheel will engagewith and be moved by the stave. In a suitable recess in the bed Bisarranged the spring or detent I-I, )rovided with ashoulder or stop, 71,to engage a pin or projection, g, on the wheel G, and having an inclinedprojection, 7 5

h, arranged in the path of the stave. The traction-wheel is alsoprovided with a pin, 9, arranged in the path of the stave immediately infront of the pin 9; or a single projection of sufficient size to occupythe space of both pins may be used.

The traction-wheel may be provided, for the purpose hereinafter stated,with a geansegment, 9' arranged to mesh with a pinion, I, mounted on ashaft, 1, having a pinion, '5, meshing with a pinion, 17, on the shaftof the feed-roller C In this case the traction-wheel will be grooved, asshown, to receive the seg ment, and the pinion I will be grooved toallow the pins 9 g to pass.

On the shaft G, and operated thereby, are mounted the adjustablewabblc-wheels or cams J, by means of which the cutter-shafts and cuttersare reciprocated. These wheels are secured on the shaft, as shown indetail in Fig. 5, the shaft being screw-threaded and grooved, as shown,and the wheel fitted loosely thereon, the aperture j, through which theshaft passes,

being flaring at each end to admit of tilting the wheel toany desiredangle, while the wheel has a projection or spline, j, which enters thegroove in the shaft to cause the wheel to rotate therewith.

J are washers loosely surrounding the shaft and having their adjacentfaces beveled, as showmand J are nuts working on the threaded portionsof the shaft. It is obvious from this construction that the wheels J maybe adjusted to different points on the shaft and there secured, and alsothat when the parts are in the position shown by'the simultaneousrotation of the washers J the wheels may be set or adjusted to thedesired angle of inclination to the axial line of the shaft.

" The cutteisK, of suitableconstruction, are

attached to the inner ends ofshafts K, mounted in boxes on slides 7a. Inorder to adjust the angle of the cutters and their shafts, each slide ismounted on ways on a bed, L, pivoted at its innerend at Z to across-piece, A, forming part of the frame, the outer end resting on anadj usting-screw, L, working in the cross-piece. To secure the bed afteradjustment, clampscrews Z pass through slots in the dependent arms Z ofthe bed and screw into the crosspiece to clamp the two in position.

The cutters are moved automatically to and from the bed B and the stavethereon by means of the wabble-wheels J, as before stated, the wheels Jpassing between guides or projections on the slides k, these guidesbeing shown in the present instance as anti-friction rollers M, mountedon a yoke or frame M, attached to the slides at or near their innerends. The cuttershafts are provided with suitable pulleys, K", by meansof suitable belting applied to which the cutters are rotated.

The operation of the machine is as follows: The guide-plates B areadjusted to suit the width of the stave, the tension on the feedrollersand pressure-roller and traction-wheel adjusted to the proper point, thebeds L adjusted to so incline the cutters as to give the proper bevel tothe edges of the stave, if any be desired, and the wheels J adjusted intheir position and inclination to correspond to the width and shape ofstave desired. The stave is then fed into the machine between theguideplates B, either by hand or, if the machine be used in conjunctionwith my other machines above specified, by the last feed-rollers of thecrozing and chamfering machine, and, being seized by the feed-rollers CG, is forced onto the knifeguides b and held thereon by thepressure-roller F, and afterward by the traction-wheel G, to prevent anywabbling or deviation from the proper line. The stave then strikes theinclined projection h, thereby lowering the spring H and its stop h,thus freeing the traction-wheel G. At the same time the stave strikesthe pin of the wheel and causes the latter to revolve. The roughenedperiphery of the wheel engages with the stave,and the continuous advanceof the latter, caused by the feed-rolls, creates a continuous rotationof the traetionwheel and shaft G, thereby causing the wabble-wheels J toactuate the slides and cutters K, so that the latter first recede andthen advance, thereby giving the desired outline and bevel to the edgeof the stave. The stave is then seized by the rear feed-rollers andcarried out of the machine, while the pin 9 on the traction-wheelengages with the now freed stop h and stops the wheel and the mechanismoperated thereby.

Then the traction-wheel has been carried around the length of the stave,it may not have reached its normal position, as shown in the drawings;but the pinion I, being in constant rotation, will be in mesh with thesegment and will bring the wheel to its proper position.

It is obvious that,although I have described my machine as intended foruse with my other machines above specified, yet it may be used alone orin conjunction with other machines of the same general character. It isalso obvious that various mechanical modifications of the constructionshown and described may be made without departing from the spirit of myinvention, and I therefore do not wish to be understood as limitingmyself to the precise details of construction shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a stave-jointer, the combination, with the traction-wheel and itsshaft, of wabble- Wheels mounted thereon and adjustable to differentangles of inclination, and slides provided with guides to embrace thesaid wheels and having cutters and cutter-shafts mounted on them,substantially as and for the purposes specified.
